摘要
彭泽鲫是一种两性型天然雌核发育群体。染色体组型分析结果表明：雌、雄鱼的染色体数目均为１６６。它们的核型组成是：３２条中部着丝点染色体、４０条亚中部着丝点染色体、１８条亚端部着丝点染色体和７６条端部着丝点染色体。臂数（ＮＦ）为２３８。本研究结果与其它雌核发育类型的鲫鱼有明显的差别。
Crucian carp (Carassius auratus) of Pengze is a bisexual natural gynogenetic. fish. Chromosome preparation was made from leucocyte culture and uncultured kindey cells by injecting PHA and colchicine in vivo. The chromosome number of crucian carp of Pengze was 166 both in male and female. The karyotype is composed of 32m, 40sm, 18st, and 76t arm number (N.F.) is 238. There are obvious differences in chromosome number and karyotype between crucian carp of Pengze and those reported in other natural gynogenetic crucian carp.
